Shaft Collars

Shaft Collars are used to position or locate a component on a shaft. In addition, Set Screw Collars and Clamp Collars can be used to limit the travel of a shaft in reciprocating applications, or used as a spacer between components. Climax Metal Products Company provides a broad assortment of Shaft Collars to suit many customer applications. Climax Shaft Collars fit imperial shaft sizes from 1/16"
through 6". Metric Shaft Collars fit shaft sizes ranging from 2mm to 80mm. Shaft Collars are made from mild steel, type 303 or 316 stainless steel, aluminum, or acetal. Steel Collars are available in multiple finishes – black oxide, clear zinc, or yellow zinc dichromate.

Set Screw Collars are the most commonly used and cost effective Shaft Collars. The holding power of a Set Screw Collar is provided by the impingement of the screw into the shaft. Lightweight styles are available for an application that has a space constraint. If additional load capacity is required, CLIMAX provides a Set Screw Collar line with a second screw at 90°. Set Screw Collars are also available with a keyway for keyed shafts.

One-Piece Clamping Collars are designed to handle applications that require a greater axial load capacity than Set Screw Collars. With one tangential screw, a one-piece Clamp Collar will not mar the shaft. Recessed screw styles of One-Piece Clamp Collars are available to provide safety with an outside surface free of major projections. End-Stop collars fit over rail assemblies on precision shafting.

Two-piece Clamp Collars are designed to handle applications that require greater axial load capacity than Set Screw and One-Piece Clamping Collars without marring the shaft. With Two tangential screws, a Two-Piece Clamp Collar can install without any major disassembly of the other components. Recessed screw styles of Two-Piece Clamping Collars are available to provide safety with an outside surface free of major projections. Two-Piece Clamp Collars can also be manufactured with a keyway for keyed shafts. Double-Wide Two-Piece Clamping Collars can be used for high axial load applications and they are also ideal for areas that are too constrained for a full-size Shaft Coupling.

Threaded Clamp Collars provide a greater amount of axial holding capacity on threaded shafts. The design fully engages the thread for secure locking. Recessed screw styles of Threaded Clamping Collars are available to provide safety with an outside surface free of major projections.
